Skyliner-250PX FlexTube™ AUTO 254mm (10") F/1200 Parabolic Truss-Tube FULLY MOTORISED auto- tracking Dobsonian Telescope   Skyliner-300P FlexTube&reade; AUTO 305mm (12") F/1500 Parabolic Truss-Tube fully motorised auto-tracking Dobsonian Telescope
"The hand controller can slew the telescope to almost any position you wish to go to...The telescope is really nippy and yet, despite the size of the OTA it’s moving, it is remarkably quiet...The automatic mode has a unique and patented override, which allows you to manually move the telescope to a position and retain the tracking when you get there. This in practice works incredibly well...This truss tube literally just slides into position and locks down, saving a huge amount of set-up time...For Lunar and planetary imagers this is a fantastic system once collimated, taking quite extreme levels of magnification... Views of the Moon during the Spring Moonwatch week had neighbours and family members enthralled... The tracking kept Saturn in the eyepiece view of a 12mm Plossl for a good hour...Through a 40mm wide-field eyepiece, deep sky objects like M31, M51 and some of spring’s globular clusters were jaw-dropping with impressive detail...All in all this is a great grab and go set-up, with the light grasp of some of my largest telescopes, yet it can be assembled and disassembled with lightning speed, dropping down to a size that can be put in the corner of a room or garage and lifted by just one person."
Astronomy Now Magazine
  "The Skyliner-300P FlexTube AUTO is a delight to use...Now it has added auto-tracking motors to the FlexTube design, taking the Dobsonian on its next great leap forward...The Skyliner’s 1500mm of focal length collapses down to just under a metre thanks to its telescopically extending trusses, making it extremely portable for such a large instrument. We were impressed to find no collimation issues even after repeated setups...With its tracking motors we could take decent images of the Moon and planets, despite the fact that long exposure imaging has never been the domain of the Dobsonian in the past...The 10mm eyepiece revealed a very refined view indeed (of Epsilon Lyrae), clearly splitting the famed star into its four components... Saturn was also a beguiling sight...The deep sky was equally striking...Messier 13, the Great Globular Cluster in Hercules was stunning....Nebulae really benefitted from the Skyliner’s light grasp...Overall, the Skyliner put in a premier performance, but the real delight is its tracking, which keeps objects in view for pretty long periods of time... This gives you all the pleasures of viewing the night sky with a larger telescope without the drawbacks...Thoroughly recommended."
